Is Kahaani a female centric movie? YES. What's the issue with that. We saw Vidya in Ishqiya, No ONe Killed Jessica, they all were female centric movie too. And she did marvelous job in all of those too.
Although Kahaani is not entertaining like "The Dirty Pictures", it's a drama-thriller in which Pregnant Vidya Balan, a software engineer who comes to Kolkata in search of her husband.
If you want to take your family to watch a movie, go for Kahaani. It won't disappoint you.
